Abstract

PURPOSE:To manufacture nondirectional silicon steel hoop having excellent magnetic characteristics, by, in continuous annealing of the silicon steel hoop made by cold rollings including intermediate annealing, controlling correlationally the annealing temp. and the elongation ratio of the steel hoop during final annealing. CONSTITUTION:Hot rolled Si steel plate contg. <4.0% Si is made into a hoop of final thickness by two repeated cold rolling processes including intermediate annealing, and is continuously annealed. The temp. T deg.C of the final continuous annealing and the elongation ratio R% of the steel hoop during the final annealing is adjusted so as to satisfy a formula (I). The steel hoop hereby manufactured is nondirectional and low in iron loss, and has an excellent magnetic characteristics.
